Watching brief of foundation trenches by J Frowde of PHFA revealed no features of archaeological significance, possibly due to the limited depth and extent of the groundworks, although twelve 19th century glass bottles were recovered during excavations following the demolition of an extension to the original school chapel.
A magnetometry survey by K Armstrong of Tigergeo confirmed the location of the known glass-working site together with possible traces of associated woodland exploitation in the north-west of the site. Centrally, various linear anomalies may relate to further industrial use of the woodland, while known former field boundaries and trackways were located to the south-east. In the same area, an undated complex of possible linear enclosures and circular anomalies was discovered that may relate to settlement or farming activity.
Evaluation by T Barton of CFA Archaeology revealed a single, very shallow linear feature containing 18th or 19th century pottery and brick.
